There's a huge functional difference between fundraising ads (no matter how manipulative) and the kind of commercial (and behavioral) ads you see everywhere else: the incentive structure it creates. Behavioral ads also require extremely intrusive tracking. Commercial ads incentivise optimising for impressions, i.e. getting users to see as many ads as possible. This leads to clickbait, bloating one-line news bits into entire articles and extending the number of clicks necessary for a user to get what they want. Social media makes this even worse by making the ads "content" (i.e. "sponsored posts") and thus trying to drive up "engagement" which in practice leads to outrage bait (because people are more likely to comment or share what they disagree with or dislike). Wikipedia on the other hand just has a slightly annoying banner made more annoying by lazy-loading (and thus shifting the layout) that shows up for a few weeks each year. Unless your complaint is with "supposedly non-profit organizations trying to make more money" (in which case I'd say your problem might be more systemic than just a website with an ad) I'd take this over the former any day.
